OBJECTIVE: Recently, selective termination is employed in multifetal pregnancies, in the presence of an abnormal fetus, or in the complication of twin pregnancies. The purpose of this study is to evaluate effectiveness, safety of the tailored selective termination in multifetal pregnancies. METHODS: This study was retrospective and involved six cases. Indication of termination were 3 cases of structural anomalies (anencephaly, encephalocele, body stalk anomaly), 1 case of chromosomal anomaly (21 trisomy) and 2 cases of monochorionic twin complications (acardiac twin, twin to twin transfusion syndrome). RESULTS: We used KCL injection in 4 cases, they were all confirmed dichorionic twin, and in 2 cases of monochorionic twin, we used alcohol ablation of intra-abdominal umbilical artery in 1 case, and radiofrequency ablation of the cord in 1 case. CONCLUSION: All procedures were successful, and all normal infants were delivered in 3rd trimester. Tailored selective termination in 2nd trimester is effective and safe in abnormal multifetal pregnancies.

OBJECTIVES: To evaluate characteristic computed tomography (CT) and magnetic resonance (MR) imaging findings of granulocytic sarcomas of the head and neck. METHODS: The CT (n=11) and MR (n=1) images obtained from 11 patients (7 males and 4 females; mean age, 23.5 yr; age range, 1 to 69 yr) with histologically-proven granulocytic sarcomas of the head and neck were retrospectively reviewed. Histological confirmation was done by bone marrow biopsy in 9 patients, and/or local biopsy in 4 patients. The imaging findings were analyzed with particular attention to location, size, shape, margin, bone destruction, internal architecture, pattern and degree of enhancement, and multiplicity of the lesions. RESULTS: The masses were most commonly located in the orbital cavity (n=8); other locations included lymph nodes (n=5) and palatine/pharyngeal/lingual tonsils (n=3). The mass sizes varied from a mean diameter of 1.3 to 5.8 cm (average, 2.6 cm). Multiple lesions were found in 6 patients. The shapes of the tumors were ovoid in 12 patients and irregular in 4 patients. Most lesions had poorly-defined margins (13/16) and invaded adjacent bony structures (5/16). On the pre-contrast CT images, the masses were iso- (5/8) or low-density (3/8) in comparison with muscle. The MRI, which was obtained in one patient in this study, showed that the mass was iso-signal intensity on T1-weighted images and iso-signal intensity on T2-weighted images compared to the gray matter of the brain. On the post-contrast CT images, there was homogenesous (n=12) or heterogeneous (n=4) enhancement, with mild (n=10), moderate (n=4), and marked (n=2) enhancement in the solid portions of the lesions. CONCLUSION: Although rare, granulocytic sarcomas arise in various locations in the head and neck area (most commonly in the orbit) in the form of well-demarcated, and mildly- and homogenously-enhancing masses with adjacent bony invasion.

BACKGROUND: Atherosclerotic cardiovascular disease and metabolic syndrome are both rapidly increasing in Koreans due to the new westernized eating habits and the aging of the population. The pulse wave velocity (PWV) reflects arterial stiffness and it may be used as an indicator of atherosclerosis. This study was conducted to investigate the association of the PWV with metabolic syndrome. METHODS: Among 1438 persons who visited the Internal Medicine Clinic or Health Center of a general hospital in Seoul, Korea, 384 adults (age range: 30-69 years old) were selected as study subjects. Those patients with cardiovascular disease or other systemic disease were excluded, but the patients with hypertension and diabetes mellitus were included. Ninety four (25.4%) subjects were classified as patients with metabolic syndrome when jointly applying the WHO Asia-Pacific criteria and NCEP ATPIII criteria. RESULTS: The PWV was higher in the older aged group and in the men compared to the other group. The greater the number of diagnostic criteria of the metabolic syndrome subjects had, the higher was their PWV. After adjustment for age, gender, blood pressure, BMI and fasting blood glucose, a PWV change of 1.0 m/sec increased the risk of metabolic syndrome by 1.31 times (95% CI: 0.81-2.09). The risk of metabolic syndrome was 7.62 times higher among the subjects with a PWV greater than 7.5 m/sec (95% CI: 1.07-54.42), as compared with that of subjects with a PWV less than 7.5 m/sec. CONCLUSIONS: The PWV may independently increase the risk of metabolic syndrome as a non-linear pattern. A prospective study needs to be conducted to confirm the meaning of PWV as a risk factor for metabolic syndrome, and especially to determine the cut off point.

PURPOSE: Lymph node metastasis is the most important prognostic factor in colorectal cancer. However, 20~30% of patients with lymph node negative colorectal cancer die of recurrent disease. We investigated whether the detection of micrometastasis is of any clinical significance in Dukes' stage A & B colorectal cancer. METHODS: Ninety patients who underwent curative resection of colorectal cancer from Aug. of 1996 to Jan. of 1999 were entered the study. For examination, we used paraffin blocks of lymph nodes which were metastasis-free by conventional histopathology. After preparation of tissue blocks using the serial sectioning technique, the specimens were stained with immunohistochemical method using anticytokeratin antibody. And the hematoxylin-eosin staining was repeated. RESULTS: We disclosed micrometastases in 15 of 90 cases, mostly located in subcapsular sinuses. And in 8 of 15 cases, we also found metastases in repeated H&E staining. There were no significant relationship between the detection of micrometastases and the depth of wall invasion, the histological grade and the status of lymphovascular invasion. With median follow-up of 15 months, we found no significant difference in recurrence between the micrometasis positive and negative groups. CONCLUSIONS: The result showed that the micrometastasis of lymph node in colorectal caner might increase the risk for development of tumor recurrence. But because of small numbers of recurrent cases and relatively short follow-up period, there was no statistically significant relationship between micrometastasis negative and positive groups.

Candida albicans as being ubiquitous human commensals produce a broad range infections depending on host immunity and its virulency, ranging from usually local mucous membrane infection to disseminated fatal candidiasis with multisystem organ failure. Recently, candidiasis of deep organ are an increasingly important nosocomial infection. Candida lung abscess is rare relatively. Most commonly, it has been stated that they are found accompanied by hematogenously disseminated candidiasis particularly in immuno- suppressed patient. Primary lung abscess caused by C. albicans has been reported in less then 15 case in worldwide, and therapeutic guideline is poorly defined. We experienced a case of a primary lung abscess by C. albicans which may developed after aspiration of oropharyngeal contents as the mechanism of entry in a malnourished elderly patient and which was treated successfully with drainage of the abscess following by administration of fluconazole for 4 weeks. Herein we report the case with a review of the literature.

BACKGROUND: The lung is the most common site of metastatic colorectal cancer comprising 10% of all curative resection of colorectal cancer. The reported 5 year survival rate varies among institutions. The purpose of the present study was to present the retrospective analysis of colorectal metastatic lung cancer surgery at our institution. MATERIAL AND METHOD: A total of 61 patients undergoing surgery for metastatic colorectal lung cancer between July 1996 and December 2003 were included in the present study. The stage of the primary colorectal cancer, site of pulmonary metastasis, method of lung resection, the number and size of the metastatic nodules, the recurrence rate, and survival were assessed. RESULT: The 3 and 5 year survival rates were 66% and 41%, respectively. No significant risk factors were identified among the studied variables by either univariate or multivariate analysis. The mean disease free survival rate was 17 months. The most common recurrent site was lung, and among these patients, 3 underwent a second operation and two are still alive. CONCLUSION: The results of the above data suggest that pulmonary resection of metastatic lung cancer in select patients after curative resection of colon cancer may be a good therapeutic option with the potential for excellent results.

PURPOSE: We undertook this study to evaluate the usefullness of radiologic placement of subcutaneous infusion ports (SIP). MATERIALS AND METHODS: Between August 1999 and May 2000 we performed 45 implantations of SIP in radiologic suite. Both sonography and fluoroscopy were used for venipuncture and to guide port insertion. We prospectively evaluated 45 systems in 45 patients with solid tumors. RESULTS: Median follow-up time was 189 days (61~352 days). Technical success rate is 100% without any venipuncture-related complications. Early complication rate within 30 days of procedure was 4.4%, including wound dehiscence (n=1) and pocket hematoma and local infection (n=1). Catheter-related infection rate was 6.7% and catheter-related venous thrombosis rate was 4.4%. Mean duration of catheter use was 208 96 days (total, 9,381 days). Overall port survival rate was 38.5%, and four systems (8.9%) were prematurely removed because of catheter tunnel infection (n=1), pocket infection (n=1), and central venous thrombosis (n=2). CONCLUSION: Radiologic placement of SIP had higher success rate and equal or lower complication rate compared with reported conventional surgical technique using anatomical landmarks. Moreover, clinical convenience, resulting from ease of scheduling could make it replace surgical method.
